VAPOR-BURNER.

Specification of Letters Patent.

Patented Apr. 5, 1910.

Application filed April 13, 1909. Serial No. 489,621.

To all whom it may concern:

Be it known that I, MARTIN GRATZ, citizen of the United States residingat Prescott, in the county of lavapai and Territory of Arizona,haveinvented certain new and useful Improvements in Vapor-Burners, ofwhich the following is a specification.

This invention relates to vapor burners and has for its object toprovide a comparatively simple and inexpensive device of this character,the construction of which is such as positively to prevent the gasoleneor other hydro-carbon from gaining access to the mixing chamber andcausing a red flame at the burner tip.

A further object of the invention is to provide a vapor generating gasfixture so constructed that a relatively long mixing chamber isprovided, the air and gas being heated subsequent to their mixture, andwhile en route to the burner, with the result that an intimate andthorough mixture of said elements and consequently the maintenance of astrong steady light are insured.

A. further object is to provide a device of the character describedincluding a generator calculated to aiford a long travel to the gasoleneor other hydro-carbon while the same is exposed to the heat of theburner, thus insuring the production of a very dry and rich gas.

A still further object of this invention is generally to improve thisclass of devices so as to increase their utility, durability andefficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions, and minordetails of construction may be resorted to within the scope of theappended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings, in which:

Figure 1 is a side elevation partly in section, of a vapor generatinggas fixture constructed in accordance with my invention. Fig. 2 is alongitudinal sectional view taken on the line 22 of Fig. 1. Fig. 3 is atransverse sectional view taken on the line 3-3 of Fig. 2. Fig. 4 is anenlarged vertical sectional view of the coupling member, and itsassociated parts.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanyingdrawings,by the same reference characters.

The improved vapor burner forming the subject matter of the presentinvention, in cludes a hanger 5, preferably in theform of a tube anddesigned to be connected to and depend from a ceiling or other suitablesupport.

Disposed at the upper end of the hanger is a tank 6 adapted'to receive aquantity of gasolene or other hydro-carbon, said tank being providedwith a removable cap 7' to permit refilling of the tank and provided atits lower end with a pipe section 8 forming a source of communicationbetween the bottom of the tank and the tubular member or hanger 5. Thelower end of the tubular member or hanger 5 extends through a coupling 9and isprovided with terminal threads 10 for engagement with thecorrespondingly threaded walls of an elbow 11 depending from thecoupling 9 as shown.

Threaded in the free end of the elbow 11 is a generator 12 the latterbeing preferably in the form of a tube, one end of which is providedwith a tip 13 having a perforation formed therein to permit the escapeof the vapor, there being a needle valve 14 disposed in advance of theelbow 11 for controlling the flow of hydro-carbon from the supply tankto the generator.

Arranged within the tubular generator 12 is a cylindrical core 15 havinga series of spaced transverse openings 16 formed therein and connectedby longitudinally disposed grooves 17 the latter being disposed instaggered relation so as to retard the flow of oil and thus allow thelatter to be thoroughly vaporized prior to its admission to thesuperheater indicated at 18. The superheater 18 is disposed above thegenerator 12 and is provided at one end with a threaded terminal 18having engagement with a correspondingly threaded nipple of the coupling9 and is bent downwardly and inwardly at its opposite end so that themouth thereof is disposed in substantially horizontal alinement with thegenerator 12.

Depending from the coupling 9 is a pipe or conductor 19 which forms ineffect a mixing chamber, and through which the mixture is conducted tothe burner tip 20. The burner 20 is disposed beneath the generator 12and superheater 18, so that after the hydro-carbon is vaporized in thegenerator 12, said vapor will be superheated by the flame from theburner 20, thus insuring a rich dry gas for delivery to the burner tip.

In using the device, the valve-14 is opened after the generator has beenheated by a torch or the like, and when sufficient gas has beengenerated to support a flame at the burner 20, said burner is lighted.hen the burner 20 is lighted the heat from the latter will heat thegenerator 12 and the generation of gas and the consumption of the sameat said burner will continue so .long as the valve 1.4: is left in openposition. Attention is here called to the fact that the superheater 18,the coupling 9, and vapor conductor 19 to gether form an air and gasmixing chamber while by reason of the mixing chamber being carrieddownwardly from its receiving end adjacent the top of the generator, theentrance of gasolene into the mixing chamber is practically precluded,and liability of any gasolene finding its way to a point below theburner is effectively obviated.

It will be noted that by reason of that portion of the mixing chamberconstituting the superheater 18 being disposed above the burner the airand gas will be heated on route to the burner with the result thatintimate and perfect union of the same will take place and a highlyinflammable gas will be produced and delivered to the burner. It willalso be noted that the hot air and gas passing through the coupling 9heats the tube or hanger 5 and the gasolene therein with the result thatthe gasolene is partially heated when it reaches the generator.

Having thus described the invention, what I claim as new, is:

1. In a vapor burner, a lamp supporting vapor conductor, a couplingsecured to said conductor, a superheater carried by the coupling, asupply pipe extending through said coupling, a generator operativelyconnected to the supply pipe, and means for controlling the admission ofoil to the generator.

2. In a vapor burner, a lamp supporting vapor conductor, a generator, asuperheater disposed above the generator, a coupling forming aconnection between the conductor, generator and superheaterrespectively, a supply pipe extending toward the coupling and a valvefor controlling the flow of oil through the supply pipe, to thegenerator.

3. I11 a vapor burner, a lamp supportmg vapor conductor, a generator, acore disposed within the generator and provided with spaced transverseopenings connected by longitudinal grooves, a superheater disposed abovethe generator and constituting a mixing chamber, a connection betweenthe gen erator, superheater and conductor, a supply pipe connected withthe interior of the generator, and a valve for controlling the admissionof oil through the supply pipe to the openings in the core.

4:. In a vapor burner, a lamp supporting vapor conductor, a couplingsecured to the conductor, a generator supported by the coupling, asuperheater disposed above the generator and having one end thereof disposed in alinement with the generator and at its opposite end connectedwith the coupling, a supply pipe extending through the couphng, a tank,a plpe section forming a source of communication between the supply pipeand tank, and a valve controlling the admission of oil to the generator.

5. In a vapor burner, a lamp supporting vapor conductor, a couplingsecured to one end of the conductor, a generator supported by thecoupling, a core disposed within the generator and provided with spacedtransverse openings connected by longitudinal grooves disposed instaggered relation to each other, a superheater disposed above thegenerator and having one end thereof secured to the coupling, and itsopposite end bent downwardly and inwardly and spaced from the free endof the generator, a pipe communicating with the interior of thegenerator, and a valve for controlling the admission of oil to thegenerator.

In testimony whereof I affix my signature in presence of two witnesses.
